Abstract

We have studied the influence of As flux on InAs nanostructures on GaAs (211)B surfaces grown by molecular beam epitaxy (MBE) at various growth temperatures (TS). It is shown that isotropic quantum dots (QDs) are formed at low TS under high As pressure condition. However, non-isotropic nanostructures, quantum dashes (QDHs), are formed under low As flux conditions. It is also shown that the sizes of nanostructure become larger with increasing TS. The shapes of nanostructure depend on As flux as well as TS.
